Wow - R18.5k for a 13" MacBook Air [-]with 256GB SSD, 1.6GHz dual core, 4GB RAM and HD 6000 graphics[/-].
I can't imagine how anyone could think that that's worth buying.
That's because you're driven by specs and paper numbers, vs what counts: Build quality, operating system, practicality and size, screen quality, battery life, backlit keyboard and trackpad quality - in no specific order. The overall experience is not determined by specs once they've surpassed a certain level.
Your opinion is without being open minded about what appeals to people who are
not specs-obsessed, who are more interested in what I have explained. It doesn't matter about what you could get in a
Windows laptop.
Of course, you probably expect Core i7, mid range GPU, 16GB RAM, etc. because that's what you 'could' get to suit your wants/needs. Or, a Windows 'equivalent' Ultrabook with Core i5, 8GB, 256 - 512GB SSD, etc.
You probably also think about your experience with Windows, and how you couldn't bare only 4GB and a >2GHz dual core. There is a significant difference between 4GB on Windows and OS X, particularly over time as Windows tends to slow down.
Go into any Mac thread, and you might find 1% of posts to be negative. The positive posts are by people in various fields, jobs, circumstances. Many contribute quality content to the forum on multiple topics.
I think they know why this stuff is worth buying, mate.
Do not confuse buying into a quality product with the certainty that it's the best all round, with "feeling smugly superior about it", to quote your friend, which I suppose you feel, too.
Once you've accepted the obvious factual differences in quality, and that things are not the 'same', you can then start looking into how OS X differs from Windows, if you want to be truly balanced. If you don't, then do us a favour and spare us of your anti Apple bubble, which I was also in for 95% of my life.
